8 Claims. (Cl. 19-159) The invention is concerned with the sliver coiling apparatus which is commonly employed in conjunction with textile draw-frames, combers and other machines in which the output material is in sliver form. Hitherto it has been customary in those of such machines having a plurality of separate delivery heads to 0011 the sliver from each head into a separate can; the object of this invention is to provide an improved form of coiling apparatus whereby the several deliveries of sliver from a plurality of heads may be coiled independently in a common can, thereby lessening the degree of supervision required from the machine attendant and reducing the work involved in the replacement of filled cans. A further advantage is the substantial saving of floor space permitted by the concentration of output i one can.

A coiling apparatus according to the invention comprises in combination a battery of coilerheads in grouped relationship, means common to the several coiler heads for rotating the sliver guides and driving the calender rollers of all the coiler heads in unison, a support for a can capable of receiving the collective output of all said coiler heads, and means operatively associated with the aforesaid driving means, for imparting to said can support a form of motion such that the can is caused to partake of a translatory movement following a circular orbit, thereby producing the desired independently coiled formation of each sliver delivered into the same.

One embodiment of the invention, as applied to a multiple coiling apparatus intended to receive a plurality of slivers, say six, from a machine such as a carding-engine or a draw frame, having six delivery heads, is illustrated in and hereinafter described with reference to the accompanying drawings. In said drawings Figs. 1 and 2 are respectively a side elevation and an end elevation of the apparatus. Fig. 3 is a plan of the coiler-head and associated mechanism after removal of the head casing, and Figs. 4, 5, 6, 7 and 8 are respectively cross-sections on the lines IVIV V-V, VIVI, VIIVII and VIIIVIII, of Fig. 3. Figs. 9 and 10 are respectively a side elevation and a plan of the basal parts of the apparatus, and Figs. 11, 12 and 13 are respectiveiy cross-sections on the lines XIXI, XIL-Xl'l and XIII-XIII of Fig. 9.

The apparatus comprises a coiler-head and a base. The coiler-head is enclosed in a casing 23 and is supported by channel-section stanchions 2|, 2| which are mounted at their feet upon longitudinal base-members 22, 22, which latter also serve to support the duplicated mechanisms (enclosed in the casings 23, 23) which are used to impart the desired translatory or orbital motion to the table or can support 2 which carries the sliver can 25.

The coiler-head incorporates six coiling units of which each comprises a pair of calender rollers 26, 21 arranged to feed a sliver to an inclined sliver guide 28 rotatable about a vertical axis. Each sliver guide 28 carries a fixed chain sprocket 29 arranged to be driven by an endless chain 33 which is common to the sprockets 29 of the other five coiler heads.

Suitable jockey or tension sprockets 3| and 3| I are provided and the chain 20 also passes around a pinion 32 which, through gearing 33, 34, imparts motion to a short counter-shaft 35 which is in turn arranged to drive two horizontal shafts 33 and 31, respectively through gear-trains 38, 39 and 40, 4|. The six coiler heads are arranged in two rows of three, and the calender roller 27 of each pair is mounted on one of said two horizontal shafts 33, 31, the other roller 26 being driven through a, gear-train 42, 43, the gear 43 being mounted on a shaft 26| of the roller 26.

Fixed to each of the jockey sprockets 3| is a gear 44 which meshes with a gear 45 on a vertical shaft 56. One of said vertical shafts 45 is driven from the machine driving shaft (not shown) of the machine with which the apparatus is associated, or by a separate motor or other driving means. Driving motion thus imparted to said vertical shaft 46 is communicated through said chain 30 to each of the sprockets 29 of the six coiler heads and through the pinion 32 and gearing 33, 34, 38, 33, and 40, 4|, to the calender roller driving shafts 38, 31 so that all the coilerheads are driven in unison.

Theseveral coiler heads are arranged to deliver into a common can which is preferably rectangular in plan form. A suitable form of can, mounted onanti-friction balls 41, is indicated at 25 in Figs. 1 and 2. The orbital movement of said can 25 necessary to achieve the desired coiled formation of the slivers delivered thereinto is brought about by mounting the can 25 upon the movable support Dr table 24 which is actuated by the mechanisms supported on the base-member 22 as hereinafter described.

The table or can support 24 consists of a stout sheet of steel shaped to provide a central troughlike portion 24! upon which the can 25 may be pushed, and at either side of said portion 2M an upstandingpart-ZM which is bent outwardly at its upper edge to form a horizontal portion 243,

as shown in Figs. 2 and 11. Each of said portions 243 of the table 24 mounts two bushes 48 and 49 which receive the crank-pins 63 and (i4 hereinafter referred to. The trough-portion 24] of the table 24 is also provided with two spaced rails Q, 50, flared apart at one end as shown in Fig. 10, to constitute a guide for a pair of downwardly projecting pegs 5'! whicmare mounted beneath the can *and which serve to ensure that the latter is placed centrally on the table.

The mechanism for imparting an orbital move-- ment to the table 25 is duplicated. Each .setaof. such mechanism is self-contained, being carried on the base-member 22 between:thezwstanchiorzs2 2|, and consists of a worm 52 at the:=base of the adjacent vertical shaft 46 by whiclidriving-mo-- tion is imparted to a worm-wheelzfiamounteden a horizontal shaft 54 at the respective ends of which are bevel-gears 55, 56. Said bevel-gears- 55, 56 respectively mesh with bevel-gears 51, 58 on twoshort:verticalashaftszS9, 69, ;carrying;disc;-.- cranksafikandfiZ; which 1atter;:are respectively-r,- furnished. with the aforesaid;.crankepinszfi i tandi, G4'whichengagesbushes "i3 and 4 the horizon-i tal part 243 of the table 24.
